Tongue base suspension using a repose bone screw system in the treatment of obstructive sleep apnea

Abstract Objectives: The aim of this study was to evaluate the tongue base suspension suture technique using a repose bone screw system with respect to efficiency in relieving obstructive sleep apnea, safety, and postoperative morbidity. Study design: This was a prospective study carried out on 10 patients with a complaint of moderate or severe obstructive sleep apnea because of retrolingual hypopharyngeal obstruction. Methods: Demographic data were determined and preoperative investigations (flexible nasopharyngoscopy, polysomnography, and lateral cephalometry) were carried out; in addition, operative technique and postoperative assessment of patients’ complaints and postoperative data of polysomnography and lateral cephalometry were carried out. Results: Improvement in the main complaints of patients, a significant reduction in the mean apnea hypopnea index in postoperative polysomnography, and an increase in the mean posterior airway space at the level of the tongue base in postoperative lateral cephalometry were recorded. Conclusion: The tongue base suspension technique using a repose bone screw system is an easy and efficient procedure for the treatment of retrolingual obstruction, with minimal postoperative morbidity. © 2013, The Egyptian Oto - Rhino - Laryngological Society.
